I keep getting them to they appear and dissapear all the time. Look a bit like bites as they are just red. Hmmm i dont know either though so not much help!
It could just be a heat rash
I don't think it's that because I have it ask day every day, but it gets worse if I get hot
My face got like that towards something i ate it was a allergic reavtion i had. Not sure if it might be the dame for you
